L-Iditol, also known as L-idit or D-dulcitol, belongs to the class of organic compounds known as sugar alcohols. These are hydrogenated forms of carbohydrate in which the carbonyl group (aldehyde or ketone, reducing sugar) has been reduced to a primary or secondary hydroxyl group. L-Iditol is soluble (in water) and a very weakly acidic compound (based on its pKa). L-Iditol has been detected in multiple biofluids, such as feces, urine, and blood. L-Iditol exists in all eukaryotes, ranging from yeast to humans. Outside of the human body, L-iditol can be found in a number of food items such as kai-lan, olive, lovage, and groundcherry. This makes L-iditol a potential biomarker for the consumption of these food products.
